"so i took a 1986 75 hp mercur
"so i took a 1986 75 hp mercury out for its maiden voyage today and got towed back to the dock after 15 minutes. the water stream shooting out the side was really weak. after getting home and checking to make sure the spit hose wasnt clogged i dropped the lower unit and replaced the impeller and all the gaskets except the bottom plate. (it was fine)the old impeller looked really good. when i put it all back together and started her up NO WATER CAME OUT THE SPIT HOLE??? what next? anybody no where i can get diagrams of an 1985/1986 75 hp mercury, is there a gasket that goes inside the top of the impeller housing? i took the lower unit back off and stuck the garden hose onto the tube the water pump housing conects to and water came streaming out of the side spit hole like crazy, so i guess there is no blockage in the hose or block... need help bad. anybody have this problem or can offer any advice?"
